Kidney cancer is also commonly known as renal cancer. It often develops silently in people, especially in its early stages. Making a timely kidney cancer diagnosis is often considered highly crucial for successful treatment outcomes. Understanding how this cancer is diagnosed and detected in the initial stages can help improve outcomes, especially for those at higher risk due to age, smoking habits, and family history of cancer.

In this article, we’ll discover more about the symptoms of kidney cancer, how this cancer is diagnosed, how this cancer is detected early and why early detection matters!

What is Kidney Cancer?

Kidney cancer is a type of cancer, and it is an abnormal growth of cells in the kidney tissue. These abnormal cells form a mass called a tumor. Cancer often begins in the kidneys when something triggers or makes a change in the cells, and they divide out of control rapidly.

Symptoms of kidney cancer

This type of cancer may not show any noticeable symptoms in its early stages. As the tumor starts to grow in the kidneys, some symptoms may begin to appear. Because of this reason, many cancer cases are often not diagnosed until it has begun to spread.

The symptoms may include:

  • Blood in the urine (Hematuria)
  • A lump or mass growing in the kidneys
  • Tiredness
  • Flank pain
  • Loss of appetite
  • Weight- loss
  • Bone pain
  • High blood pressure
  • Anemia
  • Fever
  • High calcium levels

How is kidney cancer diagnosed?

Oncologists use a combination of diagnostic tests, including imaging tests and laboratory tests, to diagnose this type of cancer. 

Here’s a list of tests and procedures used to detect this cancer, including:

Physical examinations

Doctors often review the medical history of a cancer patient and also check the symptoms, family history of cancer, and lifestyle choices. 

Performing physical examinations might reveal a mass or tenderness appearing in the kidneys. 

Urine tests

Performing urine tests helps to detect blood and the presence of abnormal cells in the urine. People take urinalysis, and urine cytology can also help to identify the symptoms. 

Blood tests

Performing blood tests helps to know more about the function of the kidney. For example, creatinine and urea levels. The levels of these substances often indicate the symptoms of anemia and abnormal liver enzymes, and they are often linked to the development of tumors in kidneys. 

Imaging tests

Performing these diagnostic tests includes imaging tests that play a significant role in diagnosing and staging these conditions. 

Some of the crucial imaging tests include:

  1. Ultrasound: After taking the first scan, taking an ultrasound test helps to reveal masses or cysts in the kidney. 
  2. CT scan: This is the standard test used for the detection of this type of cancer. Performing these tests shows the size, shape, and spread of the tumor. 
  3. MRI Scan: These scans are recommended when the CT scans are not supposed to be used in patients. 
  4. X-rays: They help to determine if the cancer has spread on other body parts (metastasis)

Biopsy tests

It involves removing a small tissue sample with the help of a needle. A biopsy is used when the imaging test results are not clear or true. A biopsy is performed to start targeted therapy.

How is this cancer detected early?

Early detection often helps to analyze incidental medical findings and proactive screenings in high-risk groups. 

Here’s how:

  • Regular health check-ups: Many cases of this type of cancer are discovered during regular routine checkups. Performing full-body health check-ups, including abdominal imaging, can reveal the presence of hidden tumors.
  • Targeted screening for High-risk groups: People with a family history of cancer or lifestyle choices such as smoking habits, high blood pressure, or certain genetic conditions, including von Hippel-Lindau disease, should need to undergo regular health checkups. 
  • Genetic testing: Performing genetic testing helps to detect some inherited health conditions that might cause this type of cancer in people. These tests are generally helpful for people from a strong family history of cancer.

Why early detection matters!

Early detection plays a key role in treating the early stage of this cancer. The early-stage kidney cancer has a five-year survival rate, which is over 90%. However, on the contrary, an advanced stage of cancer's survival rate drops below 15 to 20%. 

Here’s why early detection matters:

  • Advanced treatment options: Early detection helps to get more effective treatments, including surgery. The treatments get more successful when the tumor is small and it hasn’t spread to other body parts. 
  • Increased survival rates: Studies show that, if kidney cancer is detected in the early stages, the five-year survival rate is significantly higher. 
  • Minimally invasive treatments: The early-stage cancer can often be treated with advanced kidney surgeries. Some of these procedures involve small incisions, low levels of pain, shorter stays in hospitals, and faster recovery times. 
  • Slows down cancer progression: Early diagnosis helps to start treatments immediately without wasting any time. Cancer is a type of disease that requires urgent attention, because the delays in treatments can worsen the condition of a patient. 
  • Better treatment results: Early detection of this cancer is directly linked to the outcomes of recommended treatments in patients. The chance of recovery is high when the cancer is in its early stages.
